A practical and scalable protocol for visible‐light‐accelerated arylation and alkylation of quinoxalin‐2(1H)‐ones with hydrazines is reported. In this protocol, a hydrazone‐based two‐dimensional covalent organic frameworks (2D‐COF‐1) was employed as the heterogeneous photocatalyst (PC). Due to its excellent photocatalytic properties, good chemical stability and heterogeneous nature, the present method...
As a sustainable covalent organic framework photocatalyst, the hydrazone‐based 2D‐COF‐1 was successfully applied to the heterogeneous visible‐light‐accelerated C3 arylation and alkylation of quinoxalin‐2(1H)‐ones with hydrazines. This protocol features high efficiency, good functional group tolerance, easy scalability and remarkable catalyst reusability. It widens the applications of photoactive two‐dimensional...
